Many sendmail sites *incorrectly* prepend their site name to the From: line.
This especially bothersome when the line is in @ format, as the resulting
address is *definitely* wrong (user@site becomes relay!user@site, which *must*
be parsed as (relay!user)@site by an RFC822-compliant mailer).

To a great extent, abolition of this problem would solve the "dumb neighbor"
problem mentioned in some of the referenced articles.

I won't rehash my belief that *all* RFC822 mail transported in the UUCP domain
should be in ! format.

Don't forget that even dumb V7 mailers use the To: line if there are multiple
recipients.

Why not run sendmail on your SysV box?  There are versions available which
even include nameserver lookup code.
